A Case of Candida parapsilosis Stromal Keratitis after Descemet’s Membrane Endothelial Keratoplasty: A Case Report and Review of the Literature

ABSTRACT

A 68-year-old diabetic male with Fuchs endothelial corneal dystrophy cataract underwent combined DMEK and cataract surgery of the left eye. Post-operative course was complicated by a partial graft detachment on POD 3, treated with a re-bubbling procedure. The patient subsequently developed a corneal infiltrate, cultured by aqueous sample, that was found to be C. parapsilosis. Oral fluconazole and voriconazole, topical voriconazole 1%, and amphotericin B as well as intracameral and intrastromal voriconazole and amphotericin B were employed. By post-operative day 45, symptoms and signs of DMEK stromal C. parapsilosis keratitis had resolved, and a corneal scar remained. Best corrected visual acuity, at post-operative month 4, was 20/25-2 without correction. Post-DMEK fungal stromal keratitis is a rare post-operative complication. We present a case of C. parapsilosis DMEK stromal keratitis and describe diagnostic and therapeutic modalities that allowed for resolution of the infection, without explantation of the patient’s graft, and preservation of visual acuity.
